A weepy Tiger Woods blames golf for making him feel invincible and leading him to cheat on Elin Nordegren. “Golf is a self-centered game,” Woods writes in Newsweek. “That self-reliance made me think I could tackle the world by myself.” He adds, “The physical pain from that car accident has long healed. But the pain in my soul is more complex and unsettling.” Of his alleged mistresses, he writes, “Opportunists are trying still to cash in on my troubles, no matter how irresponsible or ridiculous their claims may be.” He lightened, though, up for his first-ever tweet yesterday, gushing to fans: “Thanks for all the love.”
